Project
CLIENT BRIEF The requirements of this project were that the development be delivered to international standards incorporating best practice specifications , due attention to human safety , as well as energy efficient design .
Systems and technologies to be utilised should be “ tried and tested ” and applicable to the project location .
Serviceability and availability of technologies implemented needed to be considered and incorporated into the engineering services design and the development therefore needed to be designed in accordance with sustainability principles ( but would not be sustainability-rated ).
Specifications also needed to take under consideration productivity and health improvement through enhanced internal environmental quality ( IEQ ).
HVAC SYSTEM The choice of system was determined by the need for detailed recovery of air conditioning costs and the level of service desired . A comparison of chilled water , VRV , water source and tempered ventilation was proposed to the client . Tempered fresh air and chilled water only was recommended to meet requirements due to efficiency and reliability , and therefore the selected HVAC system for this project was a chilled water system that incorporated ducted fan coil units and a low profile air handling system . This selection met the technology criteria for each zone of the project .
